CATSU-CAP AND METHOD OF'MAKING- THE SAME.

. l' 4 l z To all whom it may concern.' A Be it known that I, CHARLESHAMMER, 'a citizen of the United States, residing at New "York, in thecounty and State of New York,

ffm l l .-iu-larly to bottle caps of .a kind suitable for have inventedcertain new -and useful Im` provements in Catsup-Caps and Methods .ofMaking the Same,of which the following isl a specification.

vThis invention relates to closuremembers admitting of general use, andmore partic-l Icatsup. bottles, in order to seal the same.

' My invention further relates toa method forrmaking the bottle. caps.

the latter being used merely for ornamentation. The strip 8 is bentinto` the proximate form of a cylinder, as shown atl 8a in Fig. f

opposite edge being bent slightly outward as indicated at 14. The disk10 is placed- Speoiication of Letters Patent.

crimping. The outwardly turned portion 14 1s next bent or crimpedupwardly according to Figs. 3 and 4, so as to form an annular bead 15,as may be understood from F ig. 4. A portion 16 of this annular bead ismerely an edge portion of the cylindrical member 8a, but is bent overthe adjacent edge 4portion of the tongue 9. This being done a number ofindentations or impressions 17 are made in the edge of the portion 16,so as to crimp or pitch this edge firmly in place so. as to lioldthemember iirmlv in the proximate form of a cylinder. The indentations. 17may be made in various ways, as by peening, punching, or even bysubjecting the device to the pressure of the edge of a toothed wheel. Atthe same time this step is performed or at any suoseouent time asdesired, a' spiral thread 18 is formed in the lower portion of thecylindrical member, the formation of this `thread being simply thebending of the sheet metal into suitable shape for the purpose, asindicated in Fig. 6. The upper portion of the cylindrical member isprovided with a numberof ribs 19 dis* posed parallel with each other andcollectively constituting practically a milled surface for enabling theoperator to screw the cap on to a bottle or to remove the cap from saidbottle.

I do not limit myself to the precise construction shown, as variationsmay be made therefrom without departing from the spirit of my invention.

. Ha ving thus described my invention, what I claim as new and desire tosecure by Letters Patent is1- l. The method herein describedy of makingbottle caps which consists in forming a strip of sheet material providedwith a tongue eX- tending from one -end thereof, bending said form of acylinder, 'so as to 'bring said tongue close against an adjacent edgeportion of said strip, bending said edge portion of said strip over theadjacent edge portion of said tongue, crimping said edge portion andsaid tongue together, and securing a disk to one end of said cylinder.

2. The method herein described of making bottle caps, which consists informing a strip of sheet material provided with a tongue integraltherewith 'and having the proximate form of a truncated triangle,bending said strip into the proximate form clenching together one edgeof said tongue and an adjacent edge of said cylinder overlapped by saidtongue.

3. A bottle cap comprising a substantially cylindrical member of sheetmaterial having one of its edges formed into an annular bead so that aportion of said `edge overlaps another portion thereof, and a diskclosing one end of said cylindrical member.

4. A closure cap comprising a strip of sheet material bent into theproximate form of a cylinder and provided with overlapping ends, one ofsaid ends being -a tongue integral with it, said strip being providedwith an edge portion bent over the adjacent portion of said tongue andsecured thereto by crimping, and a disk closing one end of saidcylinder. j

5. A bottle cap comprising a strip vof sheet material provided withoverlapping ends and bent into the proximate form of a cylinder, saidstrip being provided with a tongue overlapping one of its ends, an edgeportion of said tongue and the adjacent edge portion of said strip beingcrimped together in o-rder to hold said strip in the proximate form of acylinder, and a disk closing one end of said cylinder.

6. A bottle capoomprising a strip of sheet material, bent into theproximate form of a cylinder and provided With overlapping ends and witha tongue integrally connected with one end and overlapping the otherend, the edge portion osaid tongue being slightly bent and overlappedbythe adjacent edge portion of said strip in order to -hold said stripin the proximate form of a cylinder, and a disk connected with theopposite edge portion 0f said cylinder, for the purpose of closing saidcylinder.

7. In a closure cap, a strip of sheet material bent into the proximatef'orm of a cylinder and provided with ends, one of which overlaps theother, said strip being further provided adjacent its ends with edgeportions, one of which overlaps the other and is lcrimped thereto.

8. In a closure cap, a lstrip' of sheet material bent linto theproximate form of a cylinder and provided With ends, one of whichoverlaps the other, said strip being further provided adjacent its endswith edge portions, one of Iwhich overlaps another so as to hold saidstrip, and a disk connected with o-ne edge of said cylinder for lclosingsaid cylinder.

9. In a closure cap, the combination of a strip of sheet materialVprovided VWith a tongue integral therewith, .said strip being providedwith ends and bent into the proximate form of a cylinder, so lthat oneend overlaps the other and that said tongue overlaps ano-ther portion ofsaid strip, one edge of said tongue and the adjacent edge of said stripoverlapped thereby being bent outwardly and crimped, said cylinder beingprovided adjacent one of its ends 4With a spirally disposed thread and adisk connected with the opposite end of said cylinder for closing thesame. Y if f l 10. The method herein described of mak ing bottle capswhich consists in giving a strip of sheet metal the approximate formof'a cylinder, and causing the ends of said strip to overlap, thenturning over the edges of the overlapping ends of said strip at one sidethereof, and subjecting said turned over edges to pressure to securethem firmly together.

In testimony whereof, I have signed name to this specification in thepresence of two subscribing witnesses,` this 9th day of May, 1914.
